Description

Technical Field

[0001] The present application relates to the technical field of double planetary mixers, and in particular to a wall scraping device for a lithium battery homogenizing double planetary mixer to prevent slurry from sticking to the wall. Background Art

[0002] The double planetary mixer is a new type of mixing and stirring equipment, in which there are two or more than three multi-layered paddle agitators in the kettle. While the agitators revolve around the axis of the kettle body, they also rotate around their own axis at different speeds, thereby achieving efficient mixing and stirring of the slurry. However, during the use of the double planetary mixer in the prior art, the slurry is easy to adhere to the inner wall of the kettle body because it does not have the function of cleaning the inner wall of the kettle body. When the water in the slurry is evaporated, it is easy to cause the inner wall of the kettle body to become compacted, which is difficult to clean and easy to damage the agitator, so it needs to be improved. Utility Model Content

[0003] In order to synchronously clean the inner wall of the kettle during the operation of the double planetary mixer, prevent the slurry from sticking to the wall, and protect the structural safety of the agitator, the present application provides a scraping device for a lithium battery homogenizing double planetary mixer to prevent the slurry from sticking to the wall.

[0004] The present application provides a lithium battery homogenizing double planetary mixer to prevent slurry from sticking to the wall. The scraping device adopts the following technical solution:

[0006] By adopting the above technical solution, during the operation of the double planetary mixer, the vertical beam will follow the planetary disk and make circular motion around the axis of the planetary disk, so that the scraper can continuously scrape the inner wall of the kettle body, effectively improving the problem of slurry adhering to the inner wall of the kettle body, saving the time for cleaning the kettle body, and protecting the structural safety of the kettle body.

[0007] Optionally, the vertical beam includes an internally hollow tube body and an end cover arranged at the bottom end of the tube body, a connecting rod is arranged in the tube body, and several scrapers are connected to the peripheral wall of the connecting rod. An outlet groove for the scraper to pass through is opened on the outer wall of the tube body facing the inner wall of the kettle body, and the outlet groove is connected to the inside of the tube body, and the end cover is detachably connected to the bottom end of the tube body.

[0008] By adopting the above technical solution, the vertical beam and the scraper are connected in a detachable manner, which makes it easy to disassemble and replace the scraper when it is damaged, without replacing the entire equipment, and has high convenience and economic benefits.

[0009] Optionally, an arc-shaped bar is provided in the outlet groove, the arc-shaped bar abuts against the inner wall of the outlet groove, and the arc-shaped bar is used to connect the scraper and the connecting rod.

[0010] By adopting the above technical solution, the arc strip is set to block the outlet groove, thereby effectively preventing the slurry from easily entering the pipe body through the outlet groove, which would make it difficult to disassemble the connecting rod from the pipe body, thereby protecting the structural safety of the vertical beam.

[0011] Optionally, a positioning block is provided on the circumferential wall at the top end of the tube body, a shaping groove is provided on the bottom wall of the planetary disk for embedding the top end of the tube body and the positioning block, a fixing tube is provided on the surface of the shaping groove along the circumferential direction, a notch is provided on the circumferential wall of the fixing tube for the positioning block to pass through, a fastening cover is threadedly connected to the circumferential wall of the fixing tube, and the tube body passes through the fastening cover.

[0012] By adopting the above technical solution, the vertical beam and the planetary disk are detachably connected, which can be quickly replaced after the vertical beam or the scraper is damaged, avoiding the replacement of the entire double planetary mixer, and has high convenience and economic benefits; the setting of the positioning block can prevent the vertical beam from deflecting, so that the scraper can always be aligned with the inner wall of the kettle body, maintaining efficient scraping operation.

[0013] Optionally, the side wall of the scraper close to the inner wall of the kettle body is provided with a rounded corner.

[0014] By adopting the above technical solution, compared with the angular scraper that is easy to scratch the inner wall of the kettle body, the rounded corners on the scraper can effectively protect the inner wall of the kettle body and extend the service life of the double planetary mixer.

[0015] Optionally, the scraper surface is covered with an anti-stick film.

[0016] By adopting the above technical solution, the anti-sticking film can isolate the scraper from the slurry, thereby preventing the slurry from sticking to the scraper surface after dehydration, which affects the scraping efficiency of the scraper, and has high practicality.

[0017] Optionally, two vertical beams are provided, the two vertical beams are symmetrically arranged about the axis of the planetary disk, and the scrapers on the two vertical beams are staggered.

[0018] By adopting the above technical solution, setting up two vertical beams can effectively improve the scraping efficiency of the slurry on the inner wall of the kettle body. The scrapers on the two vertical beams are staggered, which can improve the coverage of the scrapers on the slurry on the inner wall of the kettle body and improve the scraping effect.

[0019] Optionally, the scraper is made of a flexible material.

[0020] By adopting the above technical solution, the scraper is made of flexible material and can effectively protect the inner wall of the kettle body, preventing the scraper from scratching the inner wall of the kettle body, thereby ensuring the structural safety of the double planetary mixer and extending its service life.
